Ortho K clear vision all day without glasses, surgery or contact lenses!

Commonly referred to as Ortho K, orthokeratology is not a condition but a technique to change the shape of the cornea with the use of rigid contact lenses. Because of the advances in lens design and technology and modern manufacturing techniques, it is now possible for some people with suitable prescriptions to wear rigid lenses overnight and alter the curvature of the cornea. This can reduce or even eliminate myopia (short sightedness)! These lenses simply flatten the central cornea, steepening the mid-periphery and therefore reducing myopia. New, modern lens materials transmit enough oxygen to enable overnight wear.

Generally Ortho K is suitable for the following people, but we recommend you discuss it with your optometrist:
  • Myopes (short sightedness) up to -4.00 but depends on topography (shape) of cornea.
  • Low degree of astigmatism.
  • Young, progressing myopes.
  • Higher powers can result in partial, but not full reduction of myopia – eg, 50 year old -6.00 may benefit by being reduced to -2.00.
Others who will benefit:
  • Unsuccessful contact lens wearers.
  • Patients with dry eye who can’t tolerate lenses during the day.
  • Patients in dusty work environments.
  • Those who want refractive surgery but are either afraid, or can’t afford it.
  • Young adults showing signs of myopia progression with a family history of myopia.
  • Swimmers or those who spend a lot of time in the water.
